HI Rusty
I have tried it both ways in the box, but in reality I am not arming the motors, I have disconnected everything from the board so i did not have any outside issues causing this. I am just trying to get the board, attached only to the usb to show that it is not moving. The Rx and servo outs have all been unplugged and I am not using the Tx just usb power. That is my concern, the board, loaded with the basic quad + firmware is sitting on the floor and yet senses wild movement on 3 axis. It would seem that it should stabilize right after hitting the Zero Accel Bias button, I can't see any other settings that might impact the sensors.
Thanks
Gary

Hi Rusty
the quad has been sitting in the same place for 3 days now, just unplug the usb from the pc for power down and up, i have also used the zero accel bias dozens of times and saved and restarted, the quad does the same thing each time i start it, Flight Data Screen shows level for 2 seconds then pitch up roll left and go into a tumble for 10 minutes or so then the pitch and roll start to center and only yaw continues to show the quad rotating rapidly. Since there is no place i see to the adjust the gyros or accels other than the zero accel button I am beginning to assume the board doesn't work?
Thanks

Azred. Your gyro values are definitely way off on the scopes. When you rotate the board, do they respond at all?

Hi Rusty,
in the screen shot at 12:31:10 - 40 I am shaking the quad, lots of response from the Raw screen, only slight yaw response in the Actuals screen and the Flight Data screen showed some minor movement, but it was spinning so fast it may have been overloaded. From 40 on it is back on the ground.
Thanks

Hey guys, I'm switching my other board for the Open Pilot board. Before I do this any body had any issues with the servo on the tail. My present board is causing my tail servo to twitch alot, I cannot get the twitching out of the servo. Any recommendations?

Are you getting twitching or slop in the servo? I have my CC board on a PVC tube tri with an HS-81 servo. My servo has a little slop, but I don't notice it twitching the tail around any.

Which tail servo? I just finished a tri to add to the collection, and I started with a cheap HXT900 servo on the tail. It seems to have a twitch problem, but that's because it's trying to center with a load, or rather the weight of the motor on it. When I switched it out for a Corona 929MG servo, it got a lot less twitchier, but not completely gone. I'm thinking it's more about the servo than the board. I might just have to get something like an HS-81, which has twice the torque of the Corona servo, and there should not be as affected by the weight of the motor.

I think getting a good tail servo for a tri is a bit hit and miss. I've tried 4 different makes on my t-copter until I found one that had no centre play issues.

I'm using a direct link, so the servo arm directly drives a plastic block the motor is mounted on. Even a small amount of play in the servo can cause excessive vibrations. So far I've found a Tower Pro MG90 is pretty good. A Cronona DS-929MG and even a Hitec HS-65MG were pretty bad.
